Radiation therapy is one of the most common treatments for cancer. It uses special equipment to aim high doses of radiation at cancer cells. This damages the cancer cells and causes them to die. It can be given alone or used with other treatments, such as surgery or chemotherapy.

Radiation therapy is usually a local treatment, targeting only the tumor. The goal of radiation treatment is to damage as many cancer cells as possible, with little harm to nearby healthy tissue.
